If such apps would be able to do what it say's it did, it would have a size of Giga Bytes at least! All from XP to 2012 for both 32bit and 64bit: just impossible with 9.xMB! The MS own tools are mainly much as good enough for to do the job! Forget and not touch such apps which are provided on that way, that's simple Bulls**t!
From looking at the screen shot, it appears to be another registry cleaner/repair program and not much more. Already a crowded field. They also insist you disable all third party services before repair, which other programs don't require. The developer does seem to do a decent job of detailing of what each version update accomplishes. No generalities like "assorted bug fixes", which I hate.
